Description of the Related Art Various types of metal carriers for purifying exhaust gas, in which flat and corrugated plates made of a heat-resistant metal are alternately laminated, or a honeycomb body wound after being stacked and stored in an outer cylinder, have been developed. Some are already in practical use. The honeycomb body is usually joined at the flat portion and the crest portion and the valley portion of the corrugated plate, and as the joining means, only the arc-shaped portions of the honeycomb body are joined or joined at regular intervals. And the like (see, for example,
102744, JP-A-3-165842,

題点があった。[0003] However, in the conventional ones, since the flat body and the corrugated plate are joined over the entire length of the peaks and valleys, when the honeycomb body is housed in the outer cylinder, the binder previously applied is directed to both end faces. When the brazing agent was sprinkled, the excess brazing agent adhered to the end surface. As a result, when the brazing treatment is performed by heating, the excess brazing component diffuses into the foil of the flat plate or the corrugated sheet, and the foil itself melts together with the brazing agent, causing a problem called a missing portion called brazing. There was a point.
